Fractions - Mr Barton Maths
... Before we can look at adding fractions we need to get some practice in finding equivalent fractions. So long as you multiply the top and the bottom of a fraction by the same number you will not change its size (because all you are doing is multiplying by 1!) e.g., ...

... Moreover, using the number of decimal places to round off numbers sometime may not make a lot of sense. Example (a) can be put into a more meaningful context to illustrate this point. If your supervisor asks you to measure the width of a room, would you give him the measure in metres rounded to 3 de ...

... numbers appear in A. In this problem, however, we cannot access an entire integer in A with a single operation. The elements of A are represented in binary, and the only operation we can use to access them is “fetch the jth bit of A[i],” which takes constant time. Show that if we use only this opera ...

Elementary mathematics
Elementary mathematics consists of mathematics topics frequently taught at the primary or secondary school levels. The most basic topics in elementary mathematics are arithmetic and geometry. Beginning in the last decades of the 20th century, there has been an increased emphasis on problem solving. Elementary mathematics is used in everyday life in such activities as making change, cooking, buying and selling stock, and gambling. It is also an essential first step on the path to understanding science.In secondary school, the main topics in elementary mathematics are algebra and trigonometry. Calculus, even though it is often taught to advanced secondary school students, is usually considered college level mathematics.
